Liqui Moly 1580 Racing Bike Oil Additive 125 ml

I put half a bottle in to my bike in 2024 and immediately benefited from a smoother gear change. After an oil change in 2025 I used the other half of the bottle. The reduction in friction in the engines internals is the benefit here. I think there is a small improvement in MPG but I couldn't quantify it. I'll certainly be using it again.

I was a little dubious about this stuff, but my (all) BMW F900 engines are quite noisy, so I thought I’d give this a try. I put in the correct amount for a wet clutch & went for a ride. After 15 mins the engine definitely sounded better, less mechanical noise, & just generally sweeter. After 30 minutes I also noticed the gear changes had been smoother. Overall I’m delighted with the results.

Was very sceptical about oil adaptives but having a first jen triumph 955 that are notoriously noisy especially on tickover thought I'd try this as it was recommended by of a couple of friends that have used it in their bikes. Using the recommend amount of 20 mm (measured with a syringe) for wet clutches whent for a ride and almost five to ten minutes could tell a difference. After about 45 minutes of riding when all up to temt and mixed in I can honestly say I can tell what I would say is a big difference. Gear changes are hugely smoother, seems to spin up a lot nicer and generally vibration from engine on tickover and riding are smooth and crisp and no problems with clutch slip. I would recommend this for any one as long as you use the right amount and you'll have plenty left for oil changes or another bike.

While i am a big fan of Liqui Moly products (oils, cleaning fluids) - honestly i bought this one when it was on offer alongside some fresh oil and filter for my winter service schedule. It was a few quid and i thought " why not" . its a strange substance to use - very thick and if you try to measure it (as i had to because its a wet clutch) it 'sticks' to the measuring surface which is a bit annoying. from the first ride out in spring it made the gearbox feel significantly better! - its in a 2015 triumph speed tripe which i had really considered to have quite a clunky 'box. This has made shifts significantly better - much better than i had expected an additive to make. I've no idea what it has done to the rest of the engine, but the change to the gearbox is so good that i will definitely use this again!

I use MOs2 for my Suzuki Vstrom, and must say that it has worked amazingly on the internals of the engine. Every things is running butterly smooth. Just done an annual service from an authorised suzuki dealer, but there was still some vibrations in the bike. As soon a put MOs2 into it, the vibration almost disappeared and the bikes now giving a better fuel efficiency as well.. I would highly recommend this product. Please give it a try and see it for yourself.

All perfect!

Purchased this item for my 2002 yamaha R1 added after an oil change , wasn't sure what to expect but as yet no difference whatsoever

Works well improved gear changes
